The S1+ combines the success stories of two unique avalanche transceiver innovations: the display showing the relative position of avalanche victims and the SMART-ANTENNA-TECHNOLOGY™! Handling the device is more intuitive than ever. Once switched on, it transmits, but when opened up it switches straight to search mode. The illuminated 360° Real-Time-Display shows the position in the avalanche and gives unmistakable action instructions. As soon as the person searching begins the pinpoint search, the patented circular display and intuitive search acoustics help the location process. Located victims can now be flagged and the search can continue. Follow-up avalanche switchover and SMART-ANTENNA-TECHNOLOGY™ provide a safety plus for the user, while the economic power management protects the environment and your wallet – just two batteries are sufficient for 250 hours in transmission mode. Of course the device can be updated.
